How To Do Bas Rutten's Wind Pipe Crusher

With your opponent in front of you and their back to you, slide your lead hand underneath their jaw,
but not all the way through. Stop when your hand passes their jaw.

Step 2:

Forearm Down

Clasp your hands together, with your leading-arm hand palm facing down. Now make sure your other forearm
is on his back so he can't pull it forward. Pull your forearm straight down his back. This also creates a leverage point.

Step 3:

Pull Back

When you are ready to apply the pressure to your opponent's windpipe, pull your crushing arm's shoulder
backwards. That will apply the pressure using your forearm and crush his windpipe.
